I need my parcel returned

I made an online purchase from Totalsports, using my Foschini store card. The purchase arrived, and then some items needed to be returned. I logged a credit note and the items had to be collected from my home. The FedEx driver arrived to collect it (12/10/20) collection number (COL1T***8), and mistakably took the incorrect items to be returned. I contacted the TFG group on numerous occasions to advise them of the error. We established that the parcel (not containing any TFG brands) was at the On-The-Dot couriers. I would love to have parcel returned, as I need the items. Please help me resolve this query @TFG @FedEx @onthedot
